Hi Tom, the trick is not to use the register_images() function at all and use
'jpegImage' instead of 'SharedImage' to load a JPEG picture.
Here's the full source code for a splash screen that show in the middle for 3
seconds:
#include <fltk/SharedImage.h>
#include <fltk/Monitor.h>
#include <fltk/Window.h>
#include <fltk/run.h>
fltk::Window* splash_screen() {
fltk::Window* o = new fltk::Window(550, 400, "splash screen");
o->type(241);
o->begin();
fltk::Group* g = new fltk::Group(0, 0, 550, 400);
g->image(fltk::jpegImage::get("data/splash.jpg"));
g->resizable(o);
o->end();
o->set_non_modal();
o->clear_border();
o->resizable(o);
o->border(false);
o->Rectangle::set(fltk::Monitor::find(0,0),o->w(),o->h(),fltk::ALIGN_CENTER);
o->show();
o->flush();
do {
fltk::check();
} while (!o->visible());
return o;
}
int main(int argc, char** argv) {
const bool show_splash = true;
// open splash screen
fltk::Window* splash_window = 0;
double splash_start = fltk::get_time_secs();
splash_window = splash_screen();
splash_window->show();
// hide splash screen after 3 seconds
while(splash_window->visible() && fltk::get_time_secs() -
splash_start < 3.0)
fltk::check();
splash_window->hide();
delete splash_window;
return fltk::run();
}
